Mrs. Crocodile entered Mopatop's Shop in the episode "Mud", looking for a swamp. She was quite impressed by what the shop's swamp department had to offer everything from swamp smell, swamp sounds and water. However she thought something was missing, it turns out that the thing missing was mud. Luckily Marvin Mudmaker was also in the shop and he pointed out to her that the thing missing was mud. She decided to hire Marvin to make her some mud for her new swamp.
